Application of Sequential Pulse Combustion Control Technique to Tempering Furnace

摘要: 為了克服鋼管熱處理用回火爐傳統(tǒng)的燃燒控制方式受測(cè)量和調(diào)節(jié)環(huán)節(jié)的影響而造成的控溫精度偏差較大,爐內(nèi)溫度場(chǎng)分布不均勻等不足,采用時(shí)序脈沖燃燒控制技術(shù)來(lái)控制回火爐的爐膛溫度。重點(diǎn)介紹了時(shí)序脈沖燃燒控制系統(tǒng)的組成、工作原理及動(dòng)態(tài)性能。由于該系統(tǒng)具有控制溫度波動(dòng)小、節(jié)約燃料等優(yōu)點(diǎn),因此具有廣泛推廣的價(jià)值。

Abstract: The sequential pulse combustion control technique is used to eliminate the shortcomings of the conventional combustion control process for the tempering furnace for steel pipe heat treatment such as big accuracy deviation of the controlled temperature and uneven distribution of temperature field in the hearth which are caused by certain temperature measurement and adjustment operations of the furnace. Detailed in the paper are the main aspects of the sequential pulse combustion control system,including the configuration,operating principle and dynamic performance,etc. Thanks to its advantages such as slight fluctuation of the controlled temperature and less fuel consumption,the said system is worthy spreading.
